Abstract (en)
[origin: EP0738680A2] The system uses an endless belt conveyor (10) made of e.g. polyester and acrylic resin derivative and stretched between rollers (12,13). An electrostatic grating (32) integrated into one roller comprises two rows of electrodes (34,36) supplied from a current source (42). The generated electric field is sufficient to prevent slip of the belt on the cylindrical surface of the roller, which carries a 50 mu m insulating film (38) of e.g. silicone rubber with a high coefficient of friction. Lateral position of the belt is monitored by a detector (58) having a grid-like structure.
